Heidi Klum has a tough act to follow. The arresting supermodel stars in Sia’s new “Fire Meet Gasoline” video, the first since 12-year-old Maddie Ziegler danced provocatively in a flesh-colored leotard in two of the Aussie singer’s earlier clips.

Klum, 41, needed no body suit to conceal her modesty as she peeled off he clothes down to her black bra and panties.

She was paired with “Game of Thrones” actor Pedro Pascal, 40, to act out Sia’s searing, aptly titled love story.

The clip, featuring the third single off her new album 1000 Forms of Fear, is directed by Francesco Carrozzini. He’s a photographer and Emmy-Award-nominated director best know for his video work with Beyoncé and Nicki Minaj.

The clip opens with Heidi scooping up a handful of jewelry in a darkened bedroom and jumping in a car. She’s wearing skinny jeans and a white top, but not for long.

The video jumps back in forth with her in the car with Pascal and walking through a house wearing only a shirt and her underwear, which, incidentally, is from her own Intimates lingerie line.

They end up back at the house where Heidi splashes around gasoline. More intimate scenes follow. Heidi rolls around in bed with Pedro and looks fantastic in her underwear.

But the heated love scene becomes a little farcical when the camera slowly pans over the label to her lingerie line dangling from her panties. Yikes! Talk about product placement!

Well, Heidi doesn’t strip for nothing.

But that’s not all. In a pointed reference to Ziegler, Heidi dons a blonde wig just like the dance phenom wore in Sia’s previous videos for her songs, “Chandelier,” and “Elastic Heart.”
